Disclosed herein is a composition comprising a regioregular polyalkylthiophene and/or a regioregular poly[2,5-bis(3-alkylthiophen-2-yl)thieno(3,2-b)thiophene]; where the composition is melted and then cooled to a temperature between a melting point and a glass transition temperature of the composition; the composition having an amount of crystallinity that is at least twice the amount of crystallinity of another identical composition that is crystallized by a method that does not involve melting and cooling to a temperature between the melting point and the glass transition temperature of the identical composition.

Highly crystalline electrically conducting polymers, methods of manufacture thereof and articles comprising the same

Methods include selectively depositing a phase change resist having high light transmittance onto a dielectric to form a pattern, etching away portions of the dielectric not covered by the resist and depositing a metal seed layer on the etched portions of the dielectric. A metal layer is then deposited on the metal seed layer by light induced plating.

Inhibiting background plating

Methods of forming metal contacts with metal inks in the manufacture of photovoltaic devices are disclosed. The metal inks are selectively deposited on semiconductor coatings by inkjet and aerosol apparatus. The composite is heated to selective temperatures where the metal inks burn through the coating to form an electrical contact with the semiconductor. Metal layers are then deposited on the electrical contacts by light induced or light assisted plating.

Method for forming metal contacts

Hot melt compositions include acid waxes and acrylate functional monomers free of acid groups. Upon application of actinic radiation, the hot melt compositions cure to form and etch resist. The hot melt compositions may be used in the manufacture of printed circuit boards, optoelectronic and photovoltaic devices.

Hot melt compositions

A mask is described for forming an image on a substrate. The mask may be selectively applied to a radiant energy sensitive material on the substrate. Actinic radiation applied to the composite chemically changes portions of the radiant energy sensitive material not covered by the mask. The mask and portions of the radiant energy sensitive material are removed using a suitable aqueous base developer. The mask is composed of aqueous base soluble or dispersible polymers and light-blocking agents.
